D. 30

Answer

To determine the total number of movable vertebrae in the human body, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Vertebral Column**:
- The human vertebral column is made up of 33 individual bones known as vertebrae. These vertebrae are categorized into different regions: cervical, thoracic, lumbar, sacrum, and coccyx.

2. **Identify the Types of Vertebrae**:
- The vertebrae can be divided into:
- **Cervical Vertebrae**: 7 vertebrae
- **Thoracic Vertebrae**: 12 vertebrae
- **Lumbar Vertebrae**: 5 vertebrae
- **Sacrum**: 5 fused vertebrae
- **Coccyx**: 4 fused vertebrae

3. **Count the Movable Vertebrae**:
- The cervical, thoracic, and lumbar vertebrae are all movable.
- Therefore, the total number of movable vertebrae is:
- Cervical (7) + Thoracic (12) + Lumbar (5) = 24 movable vertebrae.

4. **Recognize the Fused Vertebrae**:
- The sacral and coccygeal vertebrae are fused, making them immovable.
- Since there are 5 sacral vertebrae and 4 coccygeal vertebrae, these do not contribute to the count of movable vertebrae.

5. **Conclusion**:
- The total number of movable vertebrae in the human body is 24.

### Final Answer:
The total number of movable vertebrae in our body is **24**.
